Good Friday turned into a great Friday for Dallas Cowboys quarterback Tony Romo.

Romo and the Cowboys agreed on a six-year contract extension that will likely keep him wearing the star on his helmet the remainder of his career.

Romo would have been in the final year of his contract in 2013. Romo’s new deal, which keeps him with the Cowboys through the 2019 season, is worth $108 million with $55 million guaranteed, sources said.

Romo has come a long way since he started his career in Dallas as an undrafted free agent out of Eastern Illinois. He now becomes the highest-paid Cowboys player in franchise history and the fifth-highest-paid player in the NFL.

Romo, who will be 33 in April, will turn 40 the April after he plays the last season of his new contract.

“There will be no greater reward, besides winning a Super Bowl, than playing my entire career as a Dallas Cowboy,” Romo said in statement. “Our goal is the Super Bowl, and I am determined and honored to be the guy in this position to help our team do that.”

Romo has often been maligned because of his lack of playoff success. Unlike previous Cowboys franchise quarterbacks Roger Staubach and Troy Aikman, Romo hasn’t led the Cowboys to Super Bowls.

In fact, Romo has won only one playoff game since he took over as the Cowboys’ starter midway through the 2006 season. However, he’s remained one of the NFL’s top quarterbacks in terms of statistics and is the Cowboys’ all-time leader with 177 touchdown passes. Romo also holds the club’s single-season records for passing yards and touchdowns.

“This is a significant day in terms of securing stability for our team for the future,” Cowboys owner Jerry Jones said in a statement. “We are very confident in this investment and commitment. Tony is uniquely qualified to lead this team … for the next several years.”

Romo met Jones at Valley Ranch about 4 p.m. Friday to officially sign his new contract.

Negotiations between the two sides really didn’t heat up until earlier this month. The Cowboys wanted to sign Romo to a contract extension last summer, but the quarterback put the talks on hold so he could concentrate on the season.

Romo had all the leverage in the contract negotiations despite his lack of playoff success because the Cowboys needed to free up salary cap space and Romo would have become an unrestricted free agent after the 2013 season.

Romo was set to count $16.8 million in 2013 against the Cowboys’ salary cap, but his new deal reduces that cap hit to $11.8 million, a source said. That frees up $5 million in salary cap space that the Cowboys can now use to pursue more free agents.

Romo last signed a contract extension with the Cowboys in 2007. That was a six-year deal for $67.4 million with $30 million guaranteed.

Romo’s new deal gives him $3 million more in guaranteed money than 28-year-old Baltimore quarterback Joe Flacco, who led the Ravens to a Super Bowl win before cashing in with a new six-year, $120.6 million contract earlier this month.

Romo will receive a $25 million signing bonus and will be paid $57 million over the first three years of the contract, according to sources.

Gonser said there was never a point in negotiations that he felt like the contract extension wouldn’t get worked out this off-season.

The pressure is now on Romo more than ever to return America’s Team to the Super Bowl.

“He knows he’s judged by winning championships and embraces that challenge and thrives on it,” Gonser said. “Tony is a special player in a quarterback-driven league. You have to have thick skin to play that position and especially for the Cowboys and in that market. He gets it. He’s focused on winning and moving forward.”

The Cowboys haven’t reached the playoffs since 2009 and finished 8-8 each of the last two years, both times losing season-ending games that cost them a postseason opportunity.

Romo said, however, he was excited about the upcoming season and some of the changes the Cowboys have made.

“This is an organization that always gives us a chance to win,” Romo said. “We haven’t had the type of success that we have all wanted the last few years, but I do know that we are on the verge of doing that. I have been around good teams and bad teams and our team is about to take that next step.”

Undoubtedly, Romo will enjoy his Easter weekend.

“Tony will be spending time with his family,” Gonser said. “He’s a man of faith, and this is a special weekend for him. He feels very thankful and very blessed.”
